Check Digit Verification of cas no
The CAS Registry Mumber 1155595-91-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,5,5,5,9 and 5 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1155595-91:
(9*1)+(8*1)+(7*5)+(6*5)+(5*5)+(4*9)+(3*5)+(2*9)+(1*1)=177
177 % 10 = 7
So 1155595-91-7 is a valid CAS Registry Number.
